In Conclusion: Check your DSLR Autofocus!
To recap, I started this article with the statement:
“You are almost certainly not getting the sharpest shots from your DSLR – and it’s not your fault!”
Hopefully, the charts I’ve shown from the Nikon D850 and Canon EOS 5D Mark IV show there is a definite need to tune a big percentage of all cameras and lenses.
On average, there’s about a 50% chance your camera/lens combination will benefit significantly from calibration – that’s the toss of a coin, for each camera & lens. With certain lenses, almost every copy will need focus calibration on your DSLR to get the performance they were designed to achieve.
If you own a few lenses and maybe more than 1 DSLR body, then I will guarantee that calibration will give you significant quality improvements on at least some of the combinations.
A last look at FoCal
Lastly, I just wanted to summarise where FoCal can come to the rescue, helping you get the performance out of the gear that you’ve paid for.

Thanks for reading
Thanks for taking the time to read this article. I hope it’s been useful, and shown the causes of DSLR autofocus issues, how you can fix them and give you some evidence for the need to do it.
We’d love to hear what you think, and what your experience is with your DSLR and lenses – have you had any that have really benefitted from tuning? Let us know in the comments!
